Abstract
Temperature effects on results of a lateral flow assay can be compensated for by measuring an environmental temperature at a testing time and a testing location, performing a lateral flow assay at the testing time and testing location to obtain an original concentration value of a target substance, and generating a modified concentration value of the target substance. The modified concentration value is generated based on the original concentration value, by compensating for a difference between the environmental temperature and ambient temperature.
Claims18
A method of compensating for temperature effects on results of a lateral flow assay, comprising:
- measuring an environmental temperature at a testing time and a testing location;
- performing a lateral flow assay at the testing time and the testing location to obtain an original concentration value of a target substance;
- and
- generating a modified concentration value of the target substance, based on the original concentration value, by compensating for a difference between the environmental temperature and ambient temperature.
A system for compensating for temperature effects on results of a lateral flow assay, the system comprising:
- a thermometer configured to measure an environmental temperature at a testing time and a testing location;
- a lateral flow reader configured to receive a lateral flow test strip at the testing time and testing location to obtain an original concentration value of a target substance;
- and
- a computing device in communication with the thermometer and the lateral flow reader and configured to generate a modified concentration value of the target substance, based on the original concentration value, by compensating for a difference between the environmental temperature and ambient temperature.
A non-transitory machine-readable medium having instructions stored thereon, which when executed by a processor, cause the processor to perform a method of compensating for temperature effects on results of a lateral flow assay, the method comprising:
- measuring an environmental temperature at a testing time and a testing location;
- performing a lateral flow assay at the testing time and the testing location to obtain an original concentration value of a target substance;
- and
- generating a modified concentration value of the target substance, based on the original concentration value, by compensating for a difference between the environmental temperature and ambient temperature.
